Boned: the story is not very far along yet (around 23 pages), but it’s promissing… maybe: A young man wakes up alone in an unknown apartment after a one night stand he remembers almost nothing about. In his jeans pocket he finds the skullring (is it a word?) his partner of the night wore, but a parrot steels it. Later, the young man is asked by his one night stand to give him the ring. He explains what happens and although his story isn’t believed, they go looking for the ring/bird.

Grayscale : citation of the “about” page : “It primarily focuses on the characters Nine and Dice, a dragon- and phoenix-shapeshifter living in the fictional corrupt city of Eterno. It’s hard to categorize it, as it contains elements from many genres: crime, horror, fantasy, sci-fi, romance, and comedy. Definitely rated M for violence, language, mild sexual content, and some disturbing themes.”

gaysome : comical comicstrips; no continuing story, but quite funny (except one page, where i found the joke a bit inappropriate)

Spectre
http://www.spectrecomic.com
In a kind of post-apocalyptic word, where the fear of some kind of deadly disease led to the creation of an upper cast oppressing the rest of the people by abducting potential sick people, we follow the life of 2 young bar employees, who are abducted by them. It focuses then on one of them, that was saved by one of the oppressors to function as what seens to heading in the direction of a sex slave, but tries to find out what happened to his friend and help him.
ca. 50 pages, but the story still isn’t very far along yet.

Charming Monsters: http://charmmonsters.thecomicseries.com/
excerpt of the “About” page:
“SO, it’s about monsters. Being charming?
…
To be honest, that’s pretty much it. This story is pretty simple, and in its simplicity lies its charm.
This story is about Noel, our poor protagonist. He’s just a normal boy, with an anormal daily life. And the anormalities are caused by the ones surrounding him, our title charming monsters, Sidney, Simon and the troupe that comes along.
But [...] why are Simon and Sidney sticking around? Why are they trying to “charm” Noel? Why is he any special?”
So, basically, it’s about 2 boymonsters fighting trying to win over a human one’s heart and become his boyfriend. Like the author said a fairly basic story. And as it just started at the end of 2012, it isn’t very long : ca 12 pages.

I still have quite a few titles to add I think, but I’ve have enough right now.
So, have a good read with all that first !
